Hisun 800 no spark

HI All,

I have an 800cc Hisun fuel injected twin cylinder. Im trying to diagnose a no spark issue.  I had a bad crank sensor, replaced that and still got no spark and yes i doubled check the new one to make sure it was good.  Checked the both coil packs and they are both receiving power, also checked the resistance and both seem to be good.  It seems to me like the ECU is not sending the signal to the Coil packs.  Anyone have any idea how to test the ECU?  Any help or advice would be appreciated.  Thanks

It has two coil packs, one for each cylinder and a crank position sensor.  I have already replaced the crank position sensor and double checked the ohm readings.  I have also checked the Coil packs and they both have identical resistance readings.  I cannot find a value for the coil packs but since they both read identically I'm leaning tword them being ok.  I also have 12v to the wires connecting to them.

      I have had my E1 since late last summer and I have always noticed that the parking brake was weak or non existent. About a month or so after I purchased it I mentioned to the dealer that the parking brake did not function well. What I was expecting from the dealer, ' well bring it in and we will correct the issue.' What I got was the typical dealer response, "it may just need to be adjusted." No shit!  Well I finally decided to adjust it. A very simple process need only two 10mm wrenches.  Open the bed, remove the pin holding the bed  to the strut and move the bad out of the way. Right in front of the electric motor is a brake disk.  That is the parking brake. It has a small set of brake pads that are actuated by a lever attached to parking brake cable.  There are two 10 mm nuts on the shaft to moves the pads. Release the inner nut and hold it in place while screwing in the outer nut - that is really a bolt. After screwing it in about one turn, tighten the other nut.  Check the parking brake. If it is holding when activated, then you are good, but if not, then you may have to turn the bolt another turn. Do not turn to far or you will lock it up.

      New to the forum. New to UTVs. New to Electric motors.  I just got a 2021 Hisun Sector E to help with moving stuff on my  steep 5 acre wooded mountain patch. Plus I thought it would be fun on the gravel roads in the "neighborhood". Because we are remote and part time to the property, I didn't want the hassle of dumping out old gas or messing with oil and filters and all the usual maintenance of a ICE. But the biggest reason for me was the noise. I test drove the Axis utvs at Tractor Supply Co and they were LOUD. Seemed to ride rough too. If you want quiet, then electric is the way to go. But it does come with a high price tag. And all the electric models are still in their infancy. So its a bit of a gamble too. I bought the property for quiet. I wanted to keep it quiet.
      I liked that the Hisun had the dry cell batteries so there is no maintenance of checking and adding water. I'm a little worried about their lifespan especially after one person's poor utube review about them. But the dealer said the company took that to heart so hopefully changes were made for better batteries. There were no Lithium battery options available anywhere near me. Polaris is supposed to have one later this year. I liked that the Hisun came standard with roof, windshield, winch and trailer hitch. I have had the sector for only one day and worked it and road it good. So far I have a big smile on my face. I wish there was a category for this model on the forum here. Meanwhile, maybe folks will share their insights/ experiences on this thread. I'd like to learn as much about the sector e as I can. There isn't much info in the owners manual.

      So my wife picked out a brand new Hisun crew 4x4 750 axis 4x4. When it gets hot it shuts off. This vehicle has less than 20 miles. I'm the dark here. First I have no access to a trouble shooting guide and have even blindly performed the "wiggle tests" as I used to do as a drive ability tech on cars professionally. I'm not able to locate what's getting overheated to cause it to shut off. After awhile it'll start right up and no issues. While trying to duplicate the problem sitting at idle, it'll eventually cut off again. Again when cooled off will start again. 
       
      I'm hating this machine and wished she'd gone with a pricier but more reliable sxs. My grizzly 550 rarely gives me issues that isn't my fault.

      Hello everyone.  I picked up a 2012 hisun strike 800 UTV.  Previous owner said that it overheated.  They were trying to drive it back to their vehicle and said it just stopped running.  He said he thought it was a blown head gasket.  They replaced fuel pump and looks like a new starter solenoid relay.   It does not have any antifreeze in the oil so don’t think its head gasket (I ordered new ones anyway). It turns over but not with a lot of juice.  (Kind of like an almost dead battery). I put in a new battery but still does the same thing.  Any thoughts?

      Good morning everyone, appreciate any help on this.  I picked up a 2013 Hisun 800 for a project.  Previous owner had fried a lot of the electrical with a bunch of aftermarket audio equipment, so I have been replacing all of the wiring to give it a fresh start.  I'm 95% there with a couple of plugs I can't figure out where they need to be routed and the reason for me reaching out for help here.
      1.  A female 2-port white plug that comes off the end of the main harness, close to the side where the terminal hook ups tap into the battery.  It has a Blue/black-stripe wire and a White/blue-stripe wire. (Pictures: https://ibb.co/m9PRDqX and
      https://ibb.co/9pHZsFj). I'm assuming it is another single offset fuse or module like the other pieces around it but can't find anything on what it might be or that wire color combination in the manual/wiring diagrams...anyone know what this guy goes to?
      2.  On the crank position sensor (torque sensor), the wires that I have coming off of that are a green wire and blue/light-gray-stripe wire (https://ibb.co/FmJLJfs)...any idea on where this guy is suppose to plug in to?
      Again, thanks for any help you can provide!

      I'm new to this forum. I recently picked up a Hisun "Coleman" Trail Tamer 800 atv that was ran way too hard. I know this is a SXS forum but I'm trying to learn as much as I can about Hisuns and there is very little out there about the ATV's. I have done a complete engine rebuild, replaced the crank, con rods, pistons, rings, head gaskets, base gaskets. cam chains, U joints, front a-arms, replaced all rear pads, repacked trailing arm bearings. Replaced the rear diff with a used one, have a rebuild kit in the cabinet. Put it all together, no spark. Somehow got spark and fuel and it started and purred like a kitten. Pulled the exhaust off to replace the gaskets, replaced the battery and starting relay switch. Turns over but no spark and no fuel again. Have taken apart almost every connection and added grease, still nothing. So jumped on this forum to try and apply any learnings from here to my project. I'm about to pull all of my hair out and Ima already going bald. Any help and input is GREATLY appreciated.
